I have searched an haven't found someone with a similar problem. Ever since I've owned the care the Autometer A/F has been pinned all the way to rich and never moves. Here is what I know:

o2s are working as they read on my laptop when connected to the EMS (have used them to tune etc) and they are well within the range of the Autometer gauge.

I have the standalone UEGO box.

I have quickly read over the pin assignments on the AEM EMS and don't see an A/F output they all seem to be inputs.

Do I need to send the signal out of the EMS by reassigning an 5v output?

Is this gauge even compatible with my setup?

I'd like to get this figured out.

I don't know where the gauge is wired too I'll try to figure this out later today, but would like to know where its supposed to go first.

Thanks in advance.
